RICHARD HENRY I-IANNAII, OF ONTARIO, CALIFORNIA, ASSIGNOR OF ONE- I'IALF TO JAMES HANNAII, SAN PEDRO, CALIFORNIA'.

WAVE-MOTOR.

SPECIFICATION forming part of Letters PatentrNo. 693,270, dated February 11, 1902.

Application liled May 9, 1901.

To @ZZ whom it ritctyconcern:

Be it known that I, RICHARD HENRY HAN- NAH, a citizen of the United States, and a resident of Ontario, in thecounty of San Bernardino and State of California, have invented a new and Improved Vave-Motor, of which the following is a full, clear, and exact description.

This invention relates to a means for deriving motive power from the action of the waves in a body of water, and the special feature of the-invention resides in certain novel devices for automatically regulating the position of the parts with respect to the varying elevations of the water due to'tides and other causes.

This speciiication is a specific description of one form ofthe invention, while the claims are deiinitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of the invention. Fig. 21is a similar View showing the .parts in dierent positions, and Fig. 3 is a sectional plan view on the line 3 3 lof Fig. 2.

The workin g parts of the apparatus are supported on a suitable framing, (indicated at an) which may and preferably does consist of spiles driven down-into the bed of thewater and connected together by cross-braces ct and a2. Between the upper and lower crossbraces a2 rigid guide-rods b pass. On these guide-rods works freely a horizontally-disposed cross-head c, connected tothe rod d of a iioat e of any suitable form. The rod d is arranged centrally between the guides b, and the iioat e is located between the spiles ct, so as to move freely up and down under the action of the waves, which will raise the iioat from the position shown in Fig. 1 to that shown in Fig. 2. 4 The rod d transmits the motive power of the apparatus, and this power may be used for compressing air, pumping water, or for any other suitable purpose. In

the drawings I haveshown the apparatus adapted for compressing air, in which connection an air-cylinder f is provided. In this 5o cylinder works a piston f', connected with the rod d at its upper end. The parts f and Serial No. 59.387. lNo model.)

f are provided withsuitable valves, which I will not describe in detail, and from the head of the cylinder f passes a flexible dischargepipe f2` for conducting the 4air to any suitable To each side v inclination, as indicated in Fig. 1, the sleevesy will grip the guides b and prevent further movement of the cylinder relatively to the guides. When, however, the armslie horizontal, as shown in Fig. 2,1the clutch-sleeves will be capable of sliding freely on the guides b. The outer ends of the arms g are provided with sleeves g2, which iit loosely on rods o', carried, respectively, by the ends of the cross-head c outside of and parallel with the guides b. The sleeves g2 have convened interior walls, enabling them to slide freely on the rod c notwithstanding that the arms g maybe at an inclination thereto or to the guides b. r Each rod c carries two tappets c2, these tappets being arranged, respectively, above and below the sleeves g2. As the float e moves up and down the piston f'V is actuated and theair is compressed in and forced from the cylinder f, as will be understood. When the float e moves downwardand carries with it the rod d and piston f to the position` shown in Fig. 1, the cylinder f drops by gravity sufficiently to inoline the arms g, and then the clutches g engage the guides b and sustain the cylinder against further downward movement. Now should the iioat fall to a point below that shown in Fig. 1, the tappets c2 at the upper ends of the rods c will strike the sleeves or boxes g2 at the outer ends of the arms g and throw down such ends of the arms, thus causing the arms to lie horizontally and causing the` clutches g to disengage the guides b. The cylinder f will then fall, downward to accommodate itself to the eXtreme downward movement of the iioat e, and when lthe tappetsczY again disengage the boxes or sleeves g2 the arms g will again be inclined and the clutches g will again become active. A reversal of the abovedescribed operation will take place should the iioat e move upward above that eleva- Ico tion which would be commensurate with the position of the cylinder. In Fig. 2 I have shown the parts during this operation-that is to say, the lower tappets c2 are engaged with the sleeves g2, and thepiston f with the upper head of the cylinder, thus holding the arms ghorizontal and permitting the cylinderf to be moved upward in time with the extreme movements of the float e.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such Variations as may lie Within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A wave-motor, comprising a float, means for utilizing the movement thereof, and sustaining devices for said means, the sustaining devices being actuated from the iioat automatically to adjust themselves to the elevation of the water.

2. In a wave-motor, the combination of a support, a float, means for utilizing the movement thereof, sustaining devices for said means, the sustaining devices comprising clutches working with the support, and tappets actuated from the float for actuating the clutches to permit the adjustment of the said means for utilizing the movement of the float.

3. In a Wave-motor, the combination of a support, a idoat, a cylinder, a rod connected with the iioat, a piston Working in the cylinder and connected with the rod, a clutch for adjustably sustaining the cylinder, and a tappet actuated from the rod and working willi 4the clutch, for the purpose specified.

4. In a wave-motor, the combination of a support, a float, a cylinder, a piston working therein, a rod connecting the piston with the float, an arm pivoted on the cylinder and having a clutch working with a part of the support adj ustably to sustain the cylinder, and a tappet actuated from the clutch and working with the arm, for the purpose specified.

5. The combination of a support, a iioat, a cylinder, a piston, a rod connecting the piston to the float, a guide-rod held on the support, an arm pivoted on the cylinder and having a clutch working on the guide-rod, a crosshead attached to the piston-rod, and a tappet sustained on the cross-head and Working with the arm ofthe cylinder, for the purpose specilied.

G. The combination of a support, comprising a guide-rod, a cylinder, an arm pivotally mounted thereon and having a clutch working with the guide-rod, a iioat, a rod connected thereto, a piston carried by the iioat-rod and working in the cylinder, a cross-head attached to the float-rod, a rod carried by-the cross-head, and tappets fastened to the crosshead rod at opposite sides of the cylinder-arm, the tappets working with said arm, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence ot two subscribing witnesses.
